A review of machine learning applications to coastal sediment transport and morphodynamics
Evan Goldstein, Giovanni Coco, Nathaniel G. Plant
2019, Earth-Science Reviews (194) 97-108
A range of computer science methods under the heading of machine learning (ML) enables the extraction of insight and quantitative relationships from multidimensional datasets. Here, we review some common ML methods and their application to studies of coastal morphodynamics and sediment transport. We examine aspects of ‘what’ and ‘why’ ML...

Telemetry is an increasingly common tool for studying the ecology of wild fish, with great potential to provide valuable information for management and conservation. For researchers to conduct a robust telemetry study, many essential considerations exist related to selecting the appropriate tag type, fish capture and tagging methods, tracking protocol,...
Rate of magma supply beneath Mammoth Mountain, California based on helium isotopes and CO2 emissions
Jennifer L. Lewicki, William C. Evans, Emily K. Montgomery-Brown, Margaret T. Mangan, John King, Andrew G. Hunt
2019, Geophysical Research Letters (46) 4636-4644
Mammoth Mountain, California, has exhibited unrest over the past ~30 years, characterized by seismicity over a broad range of depths, elevated 3He/4He ratios in fumarolic gas, and large-scale diffuse CO2 emissions. This activity has been attributed to magmatic intrusion, but minimal ground deformation and the presence of a shallow crustal gas reservoir...
Fault slip associated with the 2 September 2017 M 5.3 Sulphur Peak, Idaho, earthquake and aftershock sequence
Frederick Pollitz, Charles Wicks, William L. Yeck, James E. Evans
2019, Bulletin of the Seismological Society of America (109) 875-887
The 2 September 2017 M 5.3 Sulphur Peak, Idaho, earthquake is one of the largest earthquakes in southern Idaho since the 1983 M 6.9 Borah Peak earthquake. It was followed by a vigorous aftershock sequence for nearly two weeks that included five events above M 4.5. The coseismic and early postseismic deformation was...

Hydrocarbon reserves and technically recoverable undiscovered resources in continuous accumulations are present in Upper Ordovician strata in the Appalachian Basin Province. The province includes parts of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Georgia, and Alabama. The Upper Ordovician strata are part of the previously defined Utica-Lower...
Evaluation of a Chicken 600K SNP genotyping array in non-model species of grouse
Piotr Minias, Peter O. Dunn, Linda A. Whittingham, Jeff A. Johnson, Sara J. Oyler-McCance
2019, Scientific Reports (9)
The use of single nucleotide polymorphism (SNP) arrays to generate large SNP datasets for comparison purposes have recently become an attractive alternative to other genotyping methods. Although most SNP arrays were originally developed for domestic organisms, they can be effectively applied to wild relatives to obtain...
Role of tidal wetland stability in lateral fluxes of particulate organic matter and carbon
Neil Kamal Ganju, Zafer Defne, Tracy Elsey Quirk, Julia M. Moriarty
2019, Limnology and Oceanography (124) 1265-1277
Tidal wetland fluxes of particulate organic matter and carbon (POM, POC) are important terms in global budgets but remain poorly constrained. Given the link between sediment fluxes and wetland stability, POM and POC fluxes should also be related to stability. We measured POM and POC fluxes in...

Richard J. Moscati, Leonid A. Neymark
2019, Mineralium Deposita (55) 1-20
The Cornwall and Devon vein- and greisen-type copper and tin deposits of southwest England are spatially and genetically related to shallow-seated granitic intrusions. These late Variscan intrusions, collectively known as the Cornubian Batholith, extend over 200 km and form a continuous granitic spine from the Isles of Scilly Granite...

Shallow structure and geomorphology along the offshore northern San Andreas Fault, Tomales Point to Fort Ross, California
Samuel Johnson, Beeson Jeffrey W.
2019, Bulletin of the Seismological Society of America (109) 833-854
We mapped a poorly documented 35-km-long section of the northern San Andreas fault zone (NSAF) between Tomales Point and Fort Ross, California. Mapping is largely based on high-resolution seismic-reflection profiles (38 fault crossings), multibeam bathymetry, and onshore geology. NSAF strike in this section is nearly parallel to plate motion, characterized...
Reservoir diel water quality patterns relative to riparian shade
Leandro E. Miranda, C.D. Raines
2019, Lake and Reservoir Management (35) 148-155
Investigations into the effects of riparian shade on water quality have focused on streams, with less emphasis on natural lakes, and almost no attention given to reservoirs. In view of this gap, our objective was to assess diel water quality patterns in the nearshore zone of a reservoir and test...

Multiscale habitat factors explain variability in stream fish occurrence in the Ozark Highlands ecoregion, USA
Robert Mollenhauer, Yan Zhou, Shannon K. Brewer
2019, Copeia (107) 219-231
The dynamic, multiscale nature of stream systems makes it challenging to establish basic ecological principles to guide stream fish conservation and management. For example, finer-scale instream habitat is often constrained by coarser-scale characteristics driving observed species distributions. Additionally, instream environmental variability can result in patchy species distributions within general upstream–downstream...

Aluminum mobility in mildly acidic mine drainage: Interactions between hydrobasaluminite, silica and trace metals from the nano to the meso-scale
Manuel A. Caraballo, Richard Wanty, Philip Verplanck, Leonardo Navarro-Valdivia, Carlos Ayora, Michael Hochella
2019, Chemical Geology (519) 1-10
Aluminum precipitates control the hydrochemistry and mineralogy of a broad variety of environments on Earth (e.g., acid mine drainage, AMD, coastal wetlands, boreal and alpine streams, tropical acid sulfate soils, laterites and bauxites, …). However, the geochemical and mineralogical processes controlling Al (and other associated metals and metalloids) transport and removal in those environments...

2019, Journal of Hazardous Materials (375) 121-129
Spatial redistribution of legacy mercury (Hg) contamination in the Hackensack River estuary (New Jersey, USA) was evaluated using mercury stable isotopes. Total Hg varied from 0.06 to 3.8 µg g-1 in sediment from the tidal Hackensack River and from 15 to 154 µg g-1 near historically contaminated sites in...
Shining light on the storm: In-stream optics reveal hysteresis of dissolved organic matter character
Matthew Vaughan, William B. Bowden, James B. Shanley, Andrew W. Vermilyea, Andrew W. Schroth
2019, Biogeochemistry (143) 275-291
The quantity and character of dissolved organic matter (DOM) can change rapidly during storm events, affecting key biogeochemical processes, carbon bioavailability, metal pollutant transport, and disinfection byproduct formation during drinking water treatment. We used in situ ultraviolet–visible spectrophotometers to concurrently measure dissolved organic carbon (DOC) concentration...
Temporal and abiotic fluctuations may be preventing successful rehabilitation of soil-stabilizing biocrust communities
Kristina E. Young, Matthew A. Bowker, Sasha C. Reed, Michael C. Duniway, Jayne Belnap
2019, Ecological Applications (29)
Land degradation is a persistent ecological problem in many arid and semi-arid systems globally (drylands hereafter). Most instances of dryland degradation include some form of soil disturbance and/or soil erosion, which can hinder vegetation establishment and reduce ecosystem productivity. To combat soil erosion, researchers have identified a need...

Analysis and visualization of coastal ocean model data in the cloud
Richard P. Signell, Dharhas Pothina
2019, Journal of Marine Science and Engineering (7)
The traditional flow of coastal ocean model data is from High Performance Computing (HPC) centers to the local desktop, or to a file server where just the data needed can be extracted via services such as OPeNDAP. Analysis and visualization is then conducted using local hardware and software. This...
